KOA extends the product portfolio of Anti-Sulfuration Chip Resistors



KOA’s special anti-sulfuration resistors are intended to be used under harsh environment with high level of contamination.

KOA’s anti-sulfuration chip resistors apply high reliable material
to the inner top electrodes. This material is a new development
and has extremely high sulfuration-proof characteristics.

By the new developed inner electrode material and the technical
know-how of sulfuration-proof performances, KOA has been able
to achieve an extremely high level of sulfuration-proof

KOA’s standard resistors already contain special materials which allow
the usage in severe environment. But, if it’s intended to use products under harsh environment (under high density of sulfur), KOA recommends to use KOA’s “Anti-Sulfuration Flat Chip Resistors” as a perfect measure.
